Device for fixing the boot attachment base to a snowboard

ABSTRACT

A device for fixing a boot attachment base to a snowboard, the device including a base with a seat housing a first disc, the disc and seat having cooperating teeth. The first disc includes a rim defined about its upper surface, multi-lobed holes or apertures, and a centrally located slotted hole extend through the first disc. A second, smaller disc fits within the rim on the first disc, the second disc includes a centrally located slotted hole and multi-lobed holes. The slotted holes in the discs are disposed perpendicular to one another, the multi-lobed holes are aligned, and a locking assembly, including a parallelepiped block, fits within the holes and engages them simultaneously. A square nut, screw, and washer, complete the locking assembly for the pair of discs.

FIELD OF THE INVENTION

[0001] This invention relates to a device for fixing the boot attachment base to a snowboard.

BACKGROUND OF THE INVENTION

[0002] Plates for fixing the boot attachment base to a snowboard are known. One of these known plates consists of a disc provided along the annular edge of its lower surface with a plurality of teeth cooperating with a corresponding plurality of teeth formed on a circular seat provided in the boot attachment base.

[0003] The use of this plate requires the disc to be inserted into the base, then rested on the snowboard and fixed thereto by screw means passing through slotted holes provided in the disc.

[0004] A drawback of this known device consists of the fact that once the orientation of the attachment base relative to the longitudinal axis of the snowboard has been fixed, only its longitudinal position can be varied.

BRIEF SUMMARY OF THE INVENTION

[0005] An object of the invention is to eliminate this drawback by providing a fixing device which, while maintaining the orientation of the attachment plate relative to the snowboard fixed, enables both its longitudinal position and its traverse position to be varied relative to the snowboard. Such considerable range of adjustment is thus realized by the instant invention, in a simple, yet effective, manner.

[0006] This and other objects realized by the instant invention will be apparent from the ensuing description. The description pertains to a device for fixing the boot attachment base to a snowboard comprising:

[0007] a base provided with a seat, the edge, or perimeter, of which is provided with a plurality of teeth, said seat housing, or receiving, a first disc provided on its lower surface with a plurality of teeth that cooperate with the plurality of teeth on the perimeter of the seat;

[0008] a second disc superposed on said first disc, said first and second discs being provided centrally with slotted holes disposed mutually perpendicular, and engagable by a member slidable along said slotted holes, said first and second discs being rotatively locked relative to said base;

[0009] fixing means which pass through said first and second discs to secure the base to the snowboard.

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] A preferred embodiment of the invention is described in detail hereinafter by way of non-limiting example, with reference to the accompanying drawings, in which:

[0011]FIG. 1 is an exploded perspective view of a fixing device constructed according to the invention;

[0012]FIG. 2 is a longitudinal section therethrough mounted on the snowboard; and

[0013] FIGS. 3-5 show some of the various possible arrangements of the attachment plate relative to the snowboard, which can be obtained by the device of the invention.

DETAILED DESCRIPTION OF THE DRAWINGS

[0014] As can be seen from the figures, the device for fixing the boot attachment base to the snowboard, according to the invention, comprises substantially a first disc 2 provided along the edge of its lower surface with a plurality of teeth 4 cooperating with a corresponding plurality of teeth 6 formed on a seat 8 provided in the attachment base 10.

[0015] Specifically, the base 10 is provided with appendices 12 for securing traditional strap systems for fixing the boot.

[0016] The disc 2 is provided with a rectangular, centrally located slotted hole 14. Disc 2 further includes a plurality of lobed holes 16, and its upper surface is provided with a plurality of ribs 18 for generating friction.

[0017] An annular rim 20 extends about the upper surface of a disc 2 to contain, or receive, therein, a second disc indicated overall by reference numeral 22 and having a smaller diameter than the disc 2.

[0018] The disc 22 is also provided with a centrally located rectangular slotted hole 24 and a plurality of lobed holes 26 which, for a predetermined position, as will be apparent hereinafter, lie substantially facing the lobed holes 16 of the disc 2.

[0019] The perimetral edge bounding the hole 24 is provided with teeth 28.

[0020] The invention also comprises a locking assembly consisting of a square nut 30 and a screw 32. The square nut 30 consists of a washer 34 and a parallelepiped block 36 having dimensions such as to be able to be inserted, as an exact fit, into the slotted hole 14 of the disc 2 and into the slotted hole 24 of the disc 22, and of such a height as to engage them simultaneously.

[0021] The locking device of the invention operates in the following manner:

[0022] the base 10 is positioned on the upper surface of the snowboard 38 in the predetermined central position, after which the two discs 2 and 22 are inserted into the seat 8. The discs have already been partly secured together by the engagement of the block 36 passing through the slotted holes 14 and 24 positioned mutually perpendicular. The positions of the engagement holes for the screws 40 which fix the base to the board are then marked on the board, and the screws are screwed through a short distance, but without preventing rotation of the base, which is then orientated relative to the longitudinal axis of the snowboard 38 in such a manner as to adapt to the technical requirements of the skier.

[0023] However, before finally tightening the screws 49 it is possible, by virtue of the engagement of the block 36 guided along the two slotted holes 24 and 14, to move the disc 2 and consequently the base 10 relative to the snowboard 38, in any direction, while always maintaining its orientation to the longitudinal axis of the snowboard constant.

[0024]FIGS. 3, 4 and 5 show three of the multiplicity of configurations which the disc 2 and hence the base 10 can assume relative to the snowboard.

[0025] Intimate contact between the discs 2 and 22 is then achieved by tightly screwing the screw 32 into the square nut 30.

[0026] When the user wishes to change the position and/or orientation of the base 10 in order to vary his technique, it is sufficient to firstly slacken the screws 40, and then slacken the screw 32, to enable the base 10 to be firstly rotated into a new position and then moved relative to the fixing screws by sliding the disc 22 relative to the fixed disc 2.

[0027] Other modifications and revisions will occur to the skilled artisan in the technology to which the invention pertains. Consequently, the appended claims should be construed broadly, in a manner consistent with the scope of the invention, and should not be limited to their literal terms.
